Specification of Letters Patent.

Application filed September 5, 1919. Serial No. 321,918.

To cilia/1.0m it may concern Be it known that I. Gnonsn W. Homes, acitizen oi the United. States, residing at Dowagiac, county of Cass,State of Michigan, have invented certain. new and useful Improvementsin. Firepots, of which the "following is a specification.

This invention relates to improvements in fire pots.

The main object of this invention is to provide an improved fire pot forcooking stoves and ranges which effectively feeds air to the fuel and isvery durable in that the walls do not become overheated in use andwhich. also prevents the oven 01' adjacent parts from becoming undulyheated.

Further objects, and objects relating to structural details, willdefinitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and meansdescribed in the following specification. The invention is clearlydefined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearlyillustrated in. the accompanying drawing forming a part of thisspecification, in which:

Figure I is a detail plan view of a stove embodying the features of myinvention, portions only of the stove being illustrated.

Fig. II is a plan view of the outer wall member of the fire pot.

Fig. III is a front view thereof.

Fig. IV is a fragmentary detail perspective view showing the relation ofthe inner and outer wall members and the supporting frame.

Fig. V is a front view of one of the inner wall sections.

Fig. VI is a vertical section through the firepot wall members on a linecorresponding to line 6-6 of F ig. I.

In the drawing similar reference characters refer to similar partsthroughout the several views.

Referring to the drawing 1 represents the body of a stove such as acooking stove or range and 2 the grate of the fire pot. The rear wall ofthe fire pot comprises an outer wall member 3 having a series ofvertical inclined ribs 4 thereon and a horizontal bottom-bar 5 at thebase of the ribs providing a plurality of vertical channels 6 open atsembled and in the the rear or outer side of said; bottom bar. The outerwall member has vertical shoulders 7 at its ends and attaching ears 8.

I provide an inner wall comprising a plurality of sections 9 which aredisposed on the bar 5 between the shoulders 7 with the ends oh thesections abutting. The sections have lugs 10 which engage behind the bar5. The upper edges oi? the sections are curved rearwardly at 11 tooverhang the rear wall member. The sections have vertical air slots 12and between the slots are a series of boss-like projections 13 ofdownwardly tapered or V shape having V shaped.

recesses in their upper ends the tip of one pro ection extending intothe recess of the projection below.

With this arrangement of parts the air circulates freely through thechannels 6 and through the openings 12 of the fire pot. The projectionssupport the fuel so that the air inlets 12 are not likely to becomeclogged and so that the air can pass into the fuel. at substantially allpoints along the rear side of the fire pot, thus greatly improvingcombustion and increasing the heating capacity of the stove.

A further advantage of my construction is that the walls do not becomeunduly heated and thereby the life of the fire pot walls is greatlyincreased. And a still further advantage is that the oven at the rear ofthe fire pot is not unduly heated at this point.

The inner wall sections may be easily asevent of their burning out canbe replaced by the user as they are retained merely by seating orresting them upon the rear wall member, as illustrated.

I have shown only such parts of a stove as seem to be necessary toillustrate an embodiment or adaptation of my invention. I have notattempted to illustrate or describe other embodiments or adaptationswhich I contemplate as I believe the disclosure made will enable thoseskilled in the art to which my invention relates to embody or adapt thesame as may be desired.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is:

1. In a fire pot, the combination of an outer wall member havingvertical inclined ribs thereon and a horizontal bottom bar at PatentedMar. 22, 1921..

ti l

' the base of said ribs providing a plurality of vertical channels openat the rear of said bottom bar, said outer wall being provided withvertical shoulders at its ends and with attaching ears, and an innerwall comprising sections disposed on said bar between said shoulders andhavlng retaining lugs engaging said bar between said ribs, the upper Uedges of said inner Wall sections being curved outwardly to overhang theouter wall said inner wall sections being provided with air inletopenings. Y

2. In a fire pot,zthe combination of an outer Wall member provided withattaching members at its ends, and having vertical inclined ribs thereonand horizontal bottom bar at the base of said ribs providing a pluralityof vertical channels open at the rear of said bottom bar, and an innerwall comprising sections disposed on said bar and having retaining lugsengaging said bar be tween said ribs, the upper edges of said in- V.nerwall sect-ions being curved outwardly to overhang the outer wall,said inner wall sections being provided with air inlet openings.

.3; In a fire pot, the combination of an outer Wall member havingvertical inclined ribs thereon and a horizontal bottom bar at the baseof said ribs providing a plurality of vertical channels open at the rearof said bottom bar and an inner wall comprising sections disposed onsaid bar, the upper edges of said inner wall sections being curvedoutwardly to overhang the outer wall said inner wall sections beingprovided with air inlet openings.

4. In a fire pot, the combination oi an outer wall member provided withattaching members at its ends and having vertical ribs thereon and ahorizontal bottom bar at the base of the ribs providing a plurality ofchannels open at the bottom and close to the rear end, an inner wallt'Olllprising sections disposed on said bar, the upper edges of saidwall sections being curved rearwardly to overhang the outer wall butspaced therefrom, said inner wall sections being provided with airopenings.

In witness whereof, I have hereunto set my hand and seal in the presenceof two witnesses.
